Version bump

Bump to 0.0.11.
Make clicraft compatible with autoconf 2.59

AC_PROG_SED was introduced in 2.60.
Make documentation compatible with asciidoc 8.1.0

The old version of AsciiDoc installed on CentOS 5 through EPEL
doesn't support pass:[] or --no-xmllint.
Revert compatibility with old asciidoc

Removing --no-xmllint from a2x causes problems on other platforms,
so add it back and let CentOS 5's spec file deal with removing it.
